在此错误之前，我只允许一个用户聊天，它工作。现在，即使我尝试只放一个用户，仍然有错误.
即使备份给我同样的错误实体：

import {Column, Entity, JoinTable, ManyToMany, ManyToOne, OneToMany, OneToOne, PrimaryGeneratedColumn} from "typeorm";
import {User} from "./user.entity";
import {Order} from "./order.entity";

@Entity()
export class Chat {
    @PrimaryGeneratedColumn()
    id: number;

    @ManyToMany(() => User)
    @JoinTable()
    users: User[];

    @OneToOne(() => Order, (order) => order.chat, {nullable: true})
    order: Order
}

服务内容：

async createChat(userId, employeeId, orderId) {
        try {
            const candidateUser = await this.user.findOne({
                where: {
                    id: userId,
                },
            });

            const candidateEmployee = await this.user.findOne({
                where: {
                    id: employeeId,
                },
            });

            const candidateOrder = await this.order.findOne({
                where: {
                    id: orderId,
                },
            });

            if (candidateOrder && candidateUser && candidateEmployee) {
                const newChat = new Chat();
                newChat.users = [candidateEmployee];
                newChat.order = candidateOrder;

                const savedChat = await this.chat.save(newChat);

                candidateUser.currentChat = savedChat.id;
                candidateEmployee.currentChat = savedChat.id;

                await this.user.save(candidateUser);
                await this.user.save(candidateEmployee);

                candidateOrder.status = 'pending';

                await this.order.save(candidateOrder);

                return savedChat;
            } else {
                throw new Error('Не удалось создать чат.');
            }
        } catch (e) {
            throw new Error(e);
        }
    }
